I have a question regarding the top vent and using a controller when bringing the Akorn up to temp. I just got an UltraQ and I'm doing my first test run (no food) and tried to set a temp of 235. It overshot to around 270. I think I may have had the flue on the fan a little to open but I was also wondering about the top vent. Do you guys set the top flue to its final temp position from the get go or do you work it closed same as if you were manually controlling the temp as the Akorn is heating up? BBQ Guru advised me too use the controller to bring the smoker up to temp. Any advice is greatly appreciated.
